DE0856 : Drill String Design and Optimization

 

This practical and, highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. 

Drill string is just as important as any other tool in the well and proper designing of the appropriate one will save time and money. There are many factors to be considered when designing the correct drill string, including: well plan, casing program, rig capacity, drilling parameters and formation limits among others. 

 

Drill string design for high angle wells should be optimized for all required functions of the drill string. Optimum drillstring design requires a thorough review of well design and objectives in order to rank in importance the demands of a drill string. Practical considerations for drill string design for high angle wells and systematic approaches to the design process are presented in this state-of-the-art course. 

 

This course is designed to provide participants with an up-to-date overview of the drill string designs and optimization as well as the knowledge of how to avoid operations problems and wear on equipment. BHA design concepts, optimization, and drilling hydraulics will be covered with an emphasis on practical and safe operating procedures. Industry standards will be used as training aids to supplement the presentation material, as well as to provide participants with a thorough understanding of the drill string component operating limits and practices. 

 

By the end of the course, participants will understand the steel and submerge tubulars; the mechanical properties of steel and the basic concepts, strength and deformation; the minimum and maximum yield stress of hook’s law; the axial forces and buckling in submerged tabulars of  buoyancy; the API RP7G for drill stem design and  operating limits; the drill string and BHA failure prevention; the drill stem design, drill pipe specifications and connection; the bottom hole assembly (BHA); the drill string dynamics; the BHA selection and design; and the bending strength ratio, stiffness ratio and stress relief features. The course will also cover the BHA design for DD applications; the low-angle and high-angle design applications; the torque, drag and casing wear mitigation; the vibration monitoring and avoidance; and the handling, inspection, troubleshooting and maintenance of drill string.
